If you graded your October Meta spend on the numbers your ad platform showed you in October, you graded it months too early.
Here is what actually happened in 2025. Customers acquired from October Meta clicks were worth $222 by the end of October. By December 31 the same customers were worth $333. That is $112 of new customer value per customer that landed after the month you paid for the click.
Those October customers averaged a $167 first order but $222 of value inside October itself. They were not just converting once. They were already repeat buying within their first month. Q4's best customers do not just convert, they come back fast.
BFCM clicks showed the same shape, smaller. New customers acquired over the BFCM weekend were worth $182 when the four day window closed, and $246 by year end. A $64 rise that only shows up if you keep watching.
A 7 day cookie sees none of that $112. A 30 day window sees a fraction. In-platform attribution windows close in days, but purchases keep landing for weeks. Every platform grades its own homework, and it hands in the test before the results are in.
We tied every Meta click from Q4 2025 to the purchases it produced through December 31, with new versus repeat verified at the order level and no expiring lookback window. That is what our Attribution Time Machine does: it lets a click cohort's true value keep settling as delayed conversions arrive, instead of freezing it on the in-window snapshot.
The lag is human behavior, not a tracking artifact. Shoppers load their carts, wait for the code, and buy across the weeks that follow. So the earlier you buy the click, the more of that settle you capture before the year closes. It is one more reason to move acquisition budget earlier into October rather than waiting for the BFCM rush.
You can rebuild this exact curve from your own order history. Ask us for nLTV by click month for your Q4 2025, and put it next to this benchmark before you set 2026 budgets.

In the 2025 data, new customer value kept climbing for months. Customers from October Meta clicks were worth $222 in October and $333 by December 31, a $112 rise that lands after the click month.
Most of the value settles in the weeks after the window closes, so a 7 day cookie sees none of the $112 rise and a 30 day window sees only a fraction.
Wicked Reports ties every Meta click to the purchases it produces through year end, with new versus repeat verified at the order level and no expiring lookback, so a cohort's true value keeps settling instead of freezing on the in-window snapshot.
